Mold structure for molding housing, method for molding housing, and housing

Abstract

A mold for forming a housing having a lance includes a first mold and a second mold. The lance has a first projection for engaging a terminal and a second projection provided at a position nearer with an end of the lance than the first projection. The first mold includes a first member having a third projection. The second mold includes a second member and a third member. The second member has a first concave portion into which the third projection is inserted. The third member is configured to be moved with respect to the second member. The second member defines, with the first member, a first space where the housing is adapted to be formed. The third member defines, with the first member, a second space where the first projection and the second projection are adapted to be formed.

What is claimed is: 
     
       1. A mold for forming a housing having a lance, the lance having a first projection for engaging a terminal and a second projection provided at a position nearer with an end of the lance than the first projection, comprising:
 a first mold including a first member having a third projection; and 
 a second mold including:
 a second member having a first concave portion into which the third projection is inserted; and 
 a third member configured to be moved with respect to the second member, 
 
 wherein the second member defines, with the first member, a first space where the housing is adapted to be formed, 
 wherein the third member defines, with the first member, a second space where the first projection and the second projection are adapted to be formed, 
 wherein the second member extends further than the third member. 
 
     
     
       2. The mold as set forth in  claim 1 , wherein:
 the third member has a first part configured to form the first projection with the first member and a second part configured to form the second projection with the first member. 
 
     
     
       3. The mold as set forth in  claim 2 , wherein:
 the second part is a concave part, 
 a shape of the concave part in a cross section is triangular, the cross section defined by a direction in which the lance is elongated and a direction in which the second projection is projected from the lance.
